' WALTER E. BARNARD, OF HARTFORD, CONNECTICUT, ASSIGNOR TO UNDERWOODTYPE- WEITER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

TYPE-WRITING lVIACZ-IINE.

. a citizen of the United States, residing in Hartford, in the county ofHartford and State of Connecticut, have invented certain new and usefulLtquovcrnents in TypelVriting Machines, of which the following is aspecification.

This invention relates to the ribbon mechanisms of writing machines,especially those in which the ribbon is vibrated to cover and uncoverthe printing point at each type stroke.

()ne of the main objects of the invention is to provide simple,inexpensive and con.- veniently operated means for silencing the ribbonvibrator when it is desired to use the machine for writing stencils. Incarrying out this feature of the invention, a ribbon actuator is pivotedto the universal bar frame (which vibrates at the key strokes), and alock is provided upon the universal bar frame to prevent said actuatorfrom turning about its pivot. Thus when the lock is released, theactuator may swing idly duringthc reciprocations of the universal bar,so that no nn'ivemcnt impartedto the ribbon vibrator; while when theactuator is locked, it reciprocates with the universal bar and vibratesthe ribbon up and down to cover and uncover the printing point. The locksuitably connected to a key or fingerpiece mounted in a positionconvenient to the keyboard. Said finger-piece also controls means tosilence the ribbon-winding mechanism, so that objectionable feeding ofthe ribbon during the writing of stencils is avoided.

Another main object of the invention is to make provision for the ribbonto be wound by the action of the usual carriagedrivinp; spring, withoutincurring the drawbacks heretofore experienced with such mechanism, theprincipal of which has been due to the relatively rapid movement of theribbon during the rapid running oi. the released carriage inletter-feeding direction, as when tabulating or when performing otheroperations. To this end, I connect to the carriage-rolesing means adevice which also releases theribbon spools from the control of thecarriage spring,.so that the ribbon does not wind when the carriage isreleased. This provision is of special import-once in cases where theribbon feed is Specification of Letters Patent.

automatically reversed, since it has been found in practice that therapid movement of a carriagedriven ribbon, set up when the carriage isreleased, is obnoxious and sometimes fatal to the proper Working of theauton'iatic ribbon-reversing mechanism; the ribbon in theribbon'vibrating class of machines being usually frail and sometimesrupturing under the sudden strain occurring when the ribbon-reversingdevices chance to operate during the rapid running of the re.- leasedcarriage.

The aforesaid improvements are shown in connection with a novelribbon-reversing mechanism which is simple, inexpensive and applicableto existing machines with a moderate amount of alteration therein. Themovements of'the ribbon-reversing devices are controlled by means of afollower riding upon the coils of ribbon, to set the reversing devicesinto operation when the spool becomes empty. Objections that haveheretofore existed to the use of followers are largely overcome by myinvention. The follower is mounted upon the winding shaft to turn withthe spool, and bears against the edges of the coils of ribbon, and in nowise interferes with the detachment or attachment of the spool to thewinding shaft. To avoid liability of the follower being wrapped upwithin the coils, and for other purposes, I contrive to separate thefollower from the coils at each revolution of the spool, whereby allliability of fouling of the ribbon or of the follower is avoided. Whenthe coils of ribbon are paid oif from the spool, the follower ispermitted to enter thespool and assume a position to release a latchduring the rotation of the spool, and

thus permits the operation of the automatic devices to shift the usualdriving shaft.

Other features and advantages will hereinafter appear. In theaccompanying drawings, Figure l is a plan and Fig. 2 a front elevationof the ribbon spools, the main driving shaft, etc. Fig. 3 is a frontperspective View, showing portions of the paper carriage, the initialribbon-driving gear and its connections, the ribbon vibrator and theuniversal bar frame and connections. Fig. 4 is a front elevation showingin normal or locked position the lock for causing the ribbon to bevibrated at the type strokes. Fig. 5 is a similarview to .Fig. 4,butshows the lock released, so

Q ceases that the ribbon remains stationary or idle at the type strokes.Fig. 6 is a sectional side elevation illustrating the universal bar ashaving been moved back at the printing stroke of the type bar, and theribbon-vibrating actuator as having swung'idly about its pivot on theuniversal bar frame. Fig. 7 is a sectional side elevation similar toFig. 6, and showing the parts all in normal positions. Fig. 8'shows theuniversal bar in the same position, as at Fig. 6, and illustrates themanner in which the locked actuator I thrusts up the ribbon vibrator atthe type strokes. ,Fig. 9 is a sectional side elevation showing afragment'of the initial drive-gear of the ribbon-winding mechanism, andalso showing the manner in which it is disconnected from the remainderof the winding mechanism. Fig. l0'is a part sectional side elevationshowin principally the left hand ribbon spool an the gearing between thecarriage spring barrel and the main ribbonwinding shaft, and also thefinger-piece at thdkeyboard for silencing the ribbon-winding mechanismand the ribbon vibrator. Fig. 11 is a part sectional. plan, showing thegears extending from the spring-driving barrel to the main ribbonwinding shaft and connected parts. Fig. 12 is a plan showing the sameparts as in the left hand portion of Fig. 1, but illustrating theautomatic operation of shifting the main transverse ribbon driving shaftto connect with the left hand spool. Fig. 13 is a plan of the left hand.front corner of the machine showing the ribbon-controlling key. Fig. 14is a perspective view of the ribbon reversing. mechanism. Fig. 15 is aperspective of a ribbon spool; and Fig. 16 is a sectional side elevationof a tabulating mechanism including a carriage rack which is connectedto the ribbon operating mechanism.

In the Underwood front strike writing machine, type bars 1 strikethrough a ribbon 2 against the front side of a platen 3, the lattersuitably mounted upon a carriage, of which a part is seen at 4-. Thecarriage is propelled by a spring-barrel by means of a strap 6; A rack 7is hinged upon the carriage at 8 by means of a pair of arms 9, andmeshes with a pinion 10 connected to an escapement wheel 11. The rack isreleasable by a key lz fixed to one of the arms 9, the

i '-1 depression of said key swinging up the rack to separate it fromthe cscapemcnt pinion 10, so that it may be drawn along by thespring-barrel 5. The carriage runs upon the usual rails, one of which isseen at 13. Said ribbon 2 is wound upon a pair of similar spools 1a, 15,detachably mounted upon vertical shafts 16, 17, mounted in brackets 18,19, supported upon the fraineii o'i'lr 20 of the machine. The spoolshave central perforations to fit on the tops of the shafts, and are alsoperforated to fit upon dowelins 21 projecting up from supporting colars22 fixed on the shafts, whereby the spools are caused to rotate. Attheir lower ends, the spool-shafts carry miter gears 23.

24, to mesh alternately with similar gears specified are in common useon said U nder wood machine. The ribbon-winding devices also include aninitial drive-gear 3O fixed upon the carriage driving spring barrel 5,and meshing with a pinion 31, the latter connected by a forwardlyextending shaft 32 to a bevel pinion 33, meshin with a bcvcl pinion 3%.This pinion 34 is oosely mounted upon a transverse shaft 35, and thelatter is connected b bevel pinions 36,37 to an other forward yextending shaft 38, which carries at its forward end a bevel pinion 39,meshing with a gear i0 on the left hand end of the main transversedriving shaft 27. It will be seen that the pinion 34 is fixed to aratchet wheel 41, both these members being loose upon the shaft 35; andthat said shaft carries a fixed arm 42 upon which is pivoted a pawl 43to engage said ratchet wheel; thus permitting the spring barrel to turnback Without winding -the ribbon during the return of the carriage tobegin a new line. This arrangement also permits the ribbon to be-woundmanually independently of the carriage spring, by means of a handle44rupon the gear 40.

Disconnection may be efiected between the initial drive-gear 30 and thepinion 81, the latter being mounted for this purpose upon an arm 45hinged at i6 upon the framework of the machine. The arm 45 may be turneddown .as at Fig. 9, to' drop the pinion away from the gear; and acompression spring a7 is provided for returning the arm and pinion tonormal positions. It will be seen that during this swinging movement,the pinion 33 remains in mesh with the pinion 34. The describeddisconnection or release of the pinion 31 may be efi'ected by an arm 48fixed upon a transverse horizontal IOfik: shaft 49, suitably mountedupon the framework and carrying at its other end an arm 50, havin acam-slot 51 engageable by a screw or pin 52 formed upon the lower freeend of a lever arm 53. Said lever arm is pivoted upon the framework atfi l, so that by a swinging movement forwardly and backwardly, the arm'50 may be cammed down to rock the shaft a9 and disconnect the pinion 31.Said lever is provided with an upper arm 55 having a roll 56 to run uponthe releasable carriage rack 7, so that when the latter is lifted fromthe pinion 10, the lever 5d, 55 is vibrated, and the arm 50 is Thefinger piece rocked, and the pinion 81 disconnected from the drive-gear30, thus silencing the rihbonwinding mechanism during the rapid ruu thecarriage in letter direction. This ca *riage rack is frequently releasedby means of o tohulator-lzey 5? operating [l8- nominational str p rod 58to engage a column stop .59 upon the carriage; said column stop rodhaving a lug ts) to operate frame or 'arm 61, wl'aich in turn operates acarrying a roll .63, which lifts the rock when the tabulutor key isoperated.

Thefingerpiece 64 therefore pulls the link 6:3,swiugs the crank 66, sleeve6?, and arm 68, and by means of the lug 69 turns the crank "Z0, andhence the rock-shaft $9, to lift llll.6;tlll'14r8 and. depress thepinion Ell, Fig. 9, A spring do tenlr'll engages either 01% two notchesin the link 65 to hold the parts in either the Fig. 10 positiou or theFig. '9 position. The forward end of the link 55 is supported on a pin73, by means of a horiztuuul slot Til cut in an eulz'zrgcment of thelink. Said. finger-pi 's is used not only to silence the Wind lgmechanism, but to silence the ribbonvibrating mechanism, the latterincluding the usual u istuntliug vihrulor or ribbon carrier 76 and olever "(7 operating the some, said lever mounted on a bracket 78projecting; from :1 platen shift rail 75 us usual.

Theuniversal bur operates the usual carriage ieccl (logs (not shown). Uponan upstanding,- uriu ti l oi said ribhon-vilnnliug lever 77, isproviilcil a wrist 85, to ougug a slot 8C jloruiczl in an actuator 87Ulflliililll upon the reciprocating universal bur frame. The slot sopermits the shifting up and down ol'. the lever 84-, 77, together withthe shift. rail 79, at the case-shifting movements of the platen 3.

The actuator 8? may either swing idly about its pivot 85%, by wh ch itmounted upon an upstunclin *m 85% fixed upon the universal hur frzu'nec2 (lii' or it may move backwurcl curl torw, with the universal bur (F'4" and 8). lo the first case, the ribbon-vibrating lever 7? will remainstationary at typo strokes; while in the other use, sairl lever will beactive at the type strokes to vibrate the ribbon up and down to anduncover the printing point. This diilerence in the action of theactuator 23? is eil'ectecl hyuieuns of it looking lever 90, pivoted at;91 upon the arm till-to swing up in front of a log 92 formed on thelower end of the actuator 33', that is, the end opthe pivot as at l i s.3, l, '7 and 8. '1 the lock is depre cl, Figs. ound latter hence swingsidly about the pivot 88 while remaining in QODIHCilOH with the wristThis ellcct is shown at Fig. 6, in which the universal bar frame 82 isin its rear position, that is, the position occupied by it at thecompletion of the printing stroke of the type bur. When however thelever 90 is up in nominal position, the actuator moves with theuniversul her from the Fig. 7 to the Fig. 8 position .u each printingstroke, thereby lifting the rih-hon vibrator 76. The lever lock 90 iscontrolled by said fee(l-silcncing key (34; :1 link 93 being pivoted atits upper eml r-u' fi l to an arm of said lever 90, and at its lowerHill to the arm (38 controlled by suitl key (54-, in the manner 21-rcariy aloscrilml. l"hus said key (94 when moved forwardly from the l 10position sizuu ltuneously silences both the ribbon-vihreting mechanismand the ribbon-feeding mechanism, and the dctcnt 71 holds it 'in thisposition, so that the uninkcd types may be used for writing stencils"etc, without any movement on the port or the ribbon.

'lhe mechanism for reversing the feed of the ribbon comprises a worm 95fixed upon the ciulwisc shiltuble muiu ilriving-slmtt 27, and u tumbler95 to engage sui l worm, suiil tumbler mounted upon an arm 96, thelatlcr fixed by uiruns oi :1. hub 97 upon the lower end of a verticalrock shaft 98, alongside the spool-shaft lo; a spring 99, surroundingsaid r ick-seiiutt :uul (letcnt, tcntilug constantly to swing thetumbler 95 into mesh with the worm 5%.). This movement of the tunlblcuisnormally prcvcnteclbyu latch 100 (Fig. 10) which is pivoted upon an armlOl likcil'by a hub 102 upon the upper unil cl saitl vertical shaft 98.A draws iring 103 normally holds said latch in engugcmcnt with a. catchAll fiscal-upon the machine frame. ll; will he understood that when saidlatch is released, the shaft 98 is caused by the spring 99 to swing thetumhler 95? into engagement with the Worm 05. so that the rotation ofthe latter may force-the rotating shaft 27 longitudinally to the left tocause the gear 25 to move to or toward the gear 23; such endwisemovement of the shaft being effected by the movement of the springdetcnt cam 28 acting on the bevel collar 20. Said latch 100 isautomatically released when the ribbon is all paid off from the spool11, by the following means: A follower 105 is pivoted at 106 to thelower portion of the collar 22 on the shaft 10, and has a nose 107 whichbears up against the edges of the coils of ribbon 2 wound upon the spoolcore 108. Said'nose 107 extends up through an opening 109 in the bottomof the usual spool cup 110. and also up through any one of a series ofopenings 111, formed in the flanges of the spool. the latter as usualbeing mountable either side up upon the shaft. 10. The follower iscounter-weighted by means of an arm 112, so that the nose 107 tendsconstantly to rise within the spool.

To prevent the ribbon from becoming fouled, and the nose 10? frombecoming wrapped up in the coils of ribbon, 1 contrivc to withdraw saidnose from the coils once in each revolution of the spool; this operationbeing effected by a cam 113, which is fixed upon the framework in thepath of said arm 112. to turnthe follower to the dotted line position atFig. 10. The cam is two sided. as shown best at: lsig. 2, to operate thearm 105 when the spool is rotated in either direction.

it will be understood that the follower repeatedly taps against theribbon coils during the winding or unwinding of the ribbon from thespool; but that no function is performed by said follower until thecoils of ribbon become all or nearly all paid off, as at 10, so that thenose 107 is permitted to penetrate the spool, as shown in full lines atFig. 10. In this position of the follower, the arm 112 is enabled toengage a lip H t-formed on a. lever 115 pivoted at 116 upon theframework as at Fig. 12, and to swing said lever forwardly to engage acam. edge 11? formed on the tooth of the latch 100, thereby camniingsaid' latch down, and releasing it from the fixed catch 10%, so that thespring 99 may swing the tumbler 95 into engagementwith theshaft-shifting worm 95. hen the tumbler 95* engages the worm 95, asecond latch 118 pivoted at 119 on said tumbler drops over a catch r20fixed upon the stationary bracket 18, to hold the tumbler in engagementwith the worm, so that there is no liability of the tumbler being pushedto one side by the pressure of the worm thereon. As before explained.the shaft 27 is thrust to the left to engage the gears 23 and 25 andrewind the ribbon upon the spool 14.

Fired to the right hand end of the worm the final portion of 05 is a cam121. which comes into play as soon as the shaft 27 is shifted to theleft,'

to engage alug 122 on the latch 118, and lift the latch from the fixedcatch 120, thereby releasing the tumbler 95 Said cam 121 thereuponengages the rear or active edge of said tumbler, and presses the sameforwardly away from the worm sufficiently to enable the first latch 100to become caught upon the catch 101; this bringing the parts in positionto be reactuated the next time the spool 14 becomes empty. It will alsobe perceived that-the shaft 27 may be shifted endwise by a button 128,and also that'the gear 10. which is loosely mounted upon the shaft 27,is held against axial movement by means of a deteut 124: fixed upon thestationary bracket 18 and engaging a peripheral groove 125 formed in thehub of said wheel. A collar 126 is fixed upon the' shaft to carry a pin127 extending into a hole 128,

Fig. 11 parallel with the shaft 27 to enable the gear 10 to turn theshaft. Said lever or interponent 115, after releasing the latch 100. isswung to one side by the advancing.

arm 112 of the follower; and as soon as the lever escapes from said arm,it is returned to normal position by a sprin 129. In addition to thecounterweight of the arm 112, the follower may be provided with a sprang130, Fig. 1, to tend constantly to throw the nose 101' up into thespool.

Assoon as engagement is automaticali effected between the gears 20 and25 in the manner already described, the spool 1% be gins to turn in theopposite direction, the ribbon rewinding upon the core, and arm 112 ofthe follower riding idly 'over the cam 113, thus withdrawing the nose107 from the coils'at every revolution of the spool, and permitting thesame to bear against the coils at corresponding intervals; this idlevibration of the follower continuing 'dur' ing the winding andsubsequent unwinding of the ribbon.

The described movement of the shaft 27 to the left separates the gear 26from the gear 24, and permits the ribbon to pay off from the spool 15 asit winds on the spool 14;. When 'the spool 15 becomes empty the shaft 27moves automatically to the right to separate the gear 23, and reengagethe gears 24 and 26 to rewind the ribbon on the spool 15. This automaticmovement of the shaft :f' to the right is effected in the same manner asits movement to the left hereinhefore described; the spool 15 beingprovided with a follower 131 to release a latch 132 carried upon avertical shaft 133, which is turned by a spring 13 1 to swing a tumbler135 into engagnient with a worm 1236 fixed on said shaft 2T; said wormhaving a retaining latch 13?. and a cam 138 to lift the latch to restorethe tumbler 135 to normal position.

Variations may be resorted to Within the scope of the invention, andportions of the improvements may be used without others.
